I recognized a bunch of N64 sounds in there thats insteresting. Although I feel like I don't see any cohesion between all the songs, I would not know its the same game, alot of tracks do not seem to have some elements that groups them together. Composition wise, I think you have some work to do, some ideas are good but I feel some trouble to interpret them in a good way. I enjoyed the drum n base track Nightmare though, good job.
